Hi there, Readerirv!
First, welcome to MobileRead!
Second, welcome to the Pocket eDGe!
The eDGe has its own forum on MobileRead:
https://www.mobileread.com/forums/forumdisplay.php?f=218 and, if you haven't discovered it yet, there is a forum at
http://www.entourageedge.com/forums/forum.php you might want to peruse.
To answer your question (as best I can): You will probably want to download the Kindle app from the Amazon appstore directly to your eDGe. This allows you access to all your Kindle books and the Kindle store. It is a decent reader but it is not on the e-ink side. I am pretty sure there is no way to get the Amazon format (.azw?) books onto the e-ink side without removing the DRM (illegal?) and converting them to epub or pdf.
If forum registration gets debugged I will hope to see you on the enTourage eDGe forum where someone may have a better answer for you.
